octave: Uicontextmenu Properties

 
 15.3.3.12 Uicontextmenu Properties
 ..................................
 
 The ‘uicontextmenu’ properties are:
 
 ‘__modified__’: "off" | {"on"}
 
 ‘beingdeleted’: {"off"} | "on"
 
 ‘busyaction’: "cancel" | {"queue"}
 
 ‘buttondownfcn’: string | function handle, def. ‘[](0x0)’
      ‘buttondownfcn’ is unused.
 
 ‘callback’: def. ‘[](0x0)’
 
 ‘children’ (read-only): vector of graphics handles, def. ‘[](0x1)’
      Graphics handles of the uicontextmenu’s children.
 
 ‘clipping’: "off" | {"on"}
      If ‘clipping’ is "on", the uicontextmenu is clipped in its parent
      axes limits.
 
 ‘createfcn’: string | function handle, def. ‘[](0x0)’
      Callback function executed immediately after uicontextmenu has been
      created.  Function is set by using default property on root object,
      e.g., ‘set (0, "defaultuicontextmenucreatefcn", 'disp
      ("uicontextmenu created!")')’.
 
      For information on how to write graphics listener functions see
      SeeCallbacks section Callbacks.
 
 ‘deletefcn’: string | function handle, def. ‘[](0x0)’
      Callback function executed immediately before uicontextmenu is
      deleted.
 
      For information on how to write graphics listener functions see
      SeeCallbacks section Callbacks.
 
 ‘handlevisibility’: "callback" | "off" | {"on"}
      If ‘handlevisibility’ is "off", the uicontextmenu’s handle is not
      visible in its parent’s "children" property.
 
 ‘hittest’: "off" | {"on"}
 
 ‘interruptible’: "off" | {"on"}
 
 ‘parent’: graphics handle
      Handle of the parent graphics object.
 
 ‘position’: def. ‘[0 0]’
 
 ‘selected’: {"off"} | "on"
 
 ‘selectionhighlight’: "off" | {"on"}
 
 ‘tag’: string, def. ""
      A user-defined string to label the graphics object.
 
 ‘type’ (read-only): string
      Class name of the graphics object.  ‘type’ is always
      "uicontextmenu"
 
 ‘uicontextmenu’: graphics handle, def. ‘[](0x0)’
      Graphics handle of the uicontextmenu object that is currently
      associated to this uicontextmenu object.
 
 ‘userdata’: Any Octave data, def. ‘[](0x0)’
      User-defined data to associate with the graphics object.
 
 ‘visible’: "off" | {"on"}
      If ‘visible’ is "off", the uicontextmenu is not rendered on screen.
